The **5RS-11-R** is a specific electronic component typically identified as a **Miniature Sealed Pushbutton Switch**, often associated with the 5 series produced by manufacturers like **ITW Switches** or **Grayhill**. Below is a detailed breakdown of its specifications, construction, and typical applications. --- ## 1. Component Overview The 5RS-11-R is designed for environments where durability and protection against contaminants (dust/moisture) are required. The "R" suffix often indicates **RoHS compliance** or a specific mounting style (Rear mount). ### Technical Specifications | Feature | Description | | :--- | :--- | | **Switch Type** | Pushbutton (Momentary) | | **Circuitry** | SPST (Single Pole, Single Throw) | | **Function** | Normally Open (NO) | | **Current Rating** | Typically 100mA to 500mA @ 115VAC/28VDC | | **Sealing** | IP67 rated (Waterproof/Dustproof) | | **Termination** | Solder terminals or PC Pins | | **Mounting** | Panel Mount (Threaded Bushing) | --- ## 2. Key Physical Features ### Internal Mechanism * **Snap-Action:** Provides tactile feedback (a "click") to the user to confirm the switch has been engaged. * **Gold-Plated Contacts:** Often used in these models to ensure low contact resistance and prevent oxidation in low-power signal circuits. ### External Construction * **Housing:** Usually made of high-temperature thermoplastic or anodized aluminum. * **Seal:** Features an internal O-ring or silicone boot to prevent liquid ingress through the actuator. --- ## 3. Typical Applications Due to its ruggedized nature and small footprint, the 5RS-11-R is found in: * **Industrial Controls:** Emergency overrides or reset buttons on machinery. * **Aerospace/Defense:** Cockpit controls or handheld communication devices. * **Medical Equipment:** Interface panels that require frequent cleaning/sanitization. * **Outdoor Electronics:** Marine equipment or GPS units. --- ## 4. Part Number Breakdown (Example) While numbering varies slightly by manufacturer, the code usually breaks down as follows: * **5:** Series identifier (Miniature size). * **RS:** Rear Mount / Sealed. * **11:** Configuration code (e.g., SPST, Normally Open). * **R:** Red Button (color coding) or RoHS Compliant. ---
